SAMUEL CLOUTIER, OF LEWISTON, MAINE.

BARBERS CHAIR.

SPCIFIQATION forming part of Letters Patent No. 488,707, dated December 27, 1892.

Application led March 7 1892.

To all whom it may concern.-

Be it known that I, SAMUEL CLOUTIER, a citizen of the United States, residing at Lewiston, in the county of Androscoggin and State of Maine, have invented certain new and useful Improvments in Barbers Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of adjustable chairs which are commonly used by barbers and consists in certain improvements in the construction of the same, as hereinafter described and claimed.

In the accompanying drawings-Figure l represents a Vertical section of a chair provided with my improvements. Fig. 2 is a plan of the lower side of the seat and connections. Fig. 3 illustrates the chair seat and connections in sectional side View. Fig. p 4. represents a plate which is secured to the lower side of the seat.

The main part of the chair has the seat A, back B and arms C and is mounted on astandard g which enters a socket in the lower part of the chair on which the main part may be rotated. From the front part of the seat A depends a step E, from the outer edge of which the arms a extend upward and, to the extremities of said arms, a rest F is pivotally connected, the latter being provided with the stops b to connect with the shoulders c on said arms. The rest F maybe adj usted to extend forward or backward, and, in either direction, it will be held in alevel position by the shoulders c and stops b. A head rest d is mounted on the back B and is vertically adjustable thereon. To the lower side of the seat is made fast a plate F', to the forward edge of which is coupled a curved rack d which has a hook d at its free end. The rod c, by means of which the rack cl is connected with the plate F', has a crank-portion e at one end for the purpose hereinafter stated. The said rack is rigidly secured to the rod e which is loosely held in bearings on plate F. G indicates a plate which is coupled or hinged at its rear edge to the plate F and is rigidly attached to,

-or made solid with, a standard g on which the main chair is mounted. The plate G has a projection m on its upper surface which, when serai 110,423,997. (No model.)

of the bar h and with the lower surface of the seat. Strengthening pieces 0 are made fast to the bottom of the seat A. As will be seen, the plate G extends forward to connect with the curved rack d and the latter is retained in connection with said plate by means of the spring n, bar h and crank-portion e' on rod e; and when the lever cis moved backward,the rack d is turned from connection with plate G and the main part of the chair may be adjustedin an inclined position as shown in Fig. 1. The standard g, being circular in section7 is reduced at its lower end, forming a shoulder r, and has a series of annular grooves s, and

a vertical groove t, for the purposes' hereinafter stated.

The lower part of the chair is formed of a cylindrical, hollow body H and the legs I secured thereto. Within the body H is placed a tubular housing or support L to receive and form a socket for the standard g which rests therein and rotates with the main part of the chair. The tubular support L is provided with an annular flange or head q, which, when in place, is countersunk in the top of the body H and secured by screws. The supportLhas also formed thereon the guide u. A spring w is placed at the lower end of the standard g, said spring bearing upward against the shoulder fr' and serving to raise the standard.

.I indicates an elbow lever, pivotally connected with a plate s', fastened to the body H, said lever being provided with a foot piece y. The lever J has coupled thereto a detent r which extends through the guide u to connect with the standard g by the grooves s, for the adjustment of the chair in elevation. The standard g may be released from the detent by pressing down the foot piece y and the chair may then be adjusted.

The slot or groovetin the standard g is intended to receive the detent of a pivoted IOO lever similar in construction tothe lever J, and indicated in broken lines, J', Fig. l, being intended to prevent the rotation of the main part of the chair. Each of said levers iskept with its detent in connectionwith the standard g, by a spring extending from the body I-I, said spring being provided with a rubber cushion, as seen at o.

Bythe construction described,the main part of the chair maybe readily adj usted in elevation or in an inclined position, and may be revolved on its pedestal or locked thereto as desired.

I claim- 1. In an adjustable chair, the combination, with the chair-seat and the standard supporting base of two plates, placed onev above another, the upper plate being` fastened to the lower side of the seat, and the'lower plate being hinged to said upper plate, a rack made fast to a crank-rod which is looselycoupled to said upper plate, said rack being in position to connect with said lower plate, a bar or rod connected with said crank-rod and with a pendant connected with the seat, a spring to retain said rack in connectonwith the lower plate, a lever, connected with said pendant, and a standard rigidly connected with said lower plate and extendingV down therefrom, substantially asV and for the purposes described.

2. In a chair, the combination, with a seat and a plate F fastened thereto, of a lower plate hinged to said plate F', a standard, to the upper end of which said lower plate is made fast, a support for said standard, a curved rack d', provided with a hook at its free end and coupled to said plate F', crankrod e, in bearings carried by plate F', crankrod z', in bearings carried by the seat, a rod 7i connected with crank-rods e and z', a lever 7c, connected with rod t' at its outer end, and a spring which connects rod h with the seat, f
